I guess it might be a little different if he were ever accused of a crime... nobody ever even hinted at the fact that he was a suspect. In fact, just the opposite, the police made it known he was only wanted for questioning and that he was not a suspect. They even made it a point to restate that after they questioned him, saying he wasn't a suspect and he cooperated fully with their talks for an hour.
I mean, how dumb are NFL teams? I could see this scaring off the most conservative of owners, but how can all 32 owners weigh the risk/reward of this situation and nobody comes to the conclusion that it might be worth snagging a first round talent's rights at a much later point in the draft?
I understand he said he wouldn't sign if a team drafted him after the 3rd round, but that just wreaked of a desperation ploy by his agent to try and get a team to panic and take him on day 2. Had you taken him and approached him with common sense he would have signed with you eventually, even if it wasn't his original plan. And if not, it was worth a shot. I'll take a swing and a miss on potentially getting a big time prospect over searching for a diamond in the rough among the actual 7th round prospects out there.
